I brewed about 2.5 gallons of beer and I have it fermenting in a plastic bucket that is probably 6 gallons. My plan is to rack into my Mr. Beer after 14 days to bottle.

However I have seen little to no airlock activity in the past 24 hours - could this be due to the extra space or should I be worried?

I guess it could be a slow starting batch. The temperature was 65 when I pitched the yeast.

Air lock activity means absolutely nothing. Take Hydrometer reading over several days to make sure fermentation is occurring. You have a volume of 3.5 gal of head space and that is a lot of oxygen to push through the airlock so you may not see any activity since it is a bucket and that does not seal as well as a carboy.
